Who participated in the study. Several research institutes, including the Senger Institute, the University Hospital of Groningen, the University of the Cote d'Azur and a network of scientists called Human Cell Atlas. The results of the work of scientists were published in the specialized journal Nature Medicine.
What scientists were looking for. The researchers studied which mucous membranes contain the largest of the two specific proteins ACE2 and TMPRSS2, which COVID-19 uses to enter the human body. Scientists examined samples from the lungs, nose, eyes, intestines, heart, kidneys, and liver.
In conclusion, it is stated that among all cells, the highest concentration of these two proteins is contained in goblet and villous cells, which produce mucus in the nose.
Other coronavirus infections
These two proteins can be found in the cells of the cornea of the eye and in the intestinal mucosa. Therefore, scientists believe that there is an opportunity to get infected through the lacrimal glands, feces and oral cavity.
